Modular smartwatch Blocks made an appearance at the show -- it's something we've spent time with before. It's a neat concept: the watch face shows all kinds of incoming notifications (messages, calendar appointments, calls, and so on), but the strap is made up of swappable modules. Want GPS for your run? Simply buy a GPS-equipped module and slot it into the strap.
Just want long battery life for the watch? Build your strap simply out of four or five extra battery modules.
Augmented Acoustics is a French startup that makes headphones you wear at concerts and music festivals. The headphones are connected to the mixing desk so you hear the nuances of the music as it's played wherever you are in the venue or festival.
Carve is made up of a variety of sensors -- including an insole that slips inside your ski boot -- which track all kinds of info about your run down the mountain. Speed and GPS are logged, of course, but it'll also be able to tell how well you're turning, based on the pressure inside your boot.
